Nvidia recently held an earnings call with investors, and the subject of Nintendo Switch was brought up several times by Nvidia CEO Jen-Hsun Huang. In addition to predicting that Nvidia's relationship with Nintendo will last for decades, Huang discussed how the console's Tegra-based architecture will make bringing games to the console easier. Although Nintendo Switch doesn't use the x86 architecture of PlayStation 4 and Xbox One, Huang believes it has enough in common with the other consoles that porting games from PC will be simpler than in the past.

"The quality of games has grown significantly. And one of the factors of production value of games that has been possible is because the PC and the two game consoles, Xbox and PlayStation, and — in the near-future — the Nintendo Switch, all of these architectures are common in the sense that they all use modern GPUs, they all use programmable shading, and they all have basically similar features. As a result of that, game developers can target a much larger installed base with one common code base and, as a result, they can increase the production quality, production value of the games."

Wii U differed so greatly from PlayStation 4 and Xbox One in terms of hardware that porting a game to the console was almost as much work as creating a new game from the ground up for some developers. Hopefully that won't be the case with Nintendo Switch.
